My baby (A 2000 Honda Civic Si), is making a ticking noise when it warms up. I only notice it if my foot is on the gas. It is hard to describe, but it definitely doesn't sound like an exhaust problem. If I'm listening to music, I won't even hear it. I used to only notice it when I was going uphill or giving it a lot of gas, but now I notice it more. If I'm at a stop light, or giving it a little gas at idle, I don't hear the noise. Does the valve need to be adjusted? All the scheduled maintenance has been done recently (timing belt, water pump, my clutch, the ignition system
The symptoms you described are textbook symptoms of a car in need of a valve adjustment. Most Japanese cars of this era used mechanical lifters, as opposed to hydraulic lifters found in many European cars. The upside of mechanical lifters is better long term reliability and better high rpm performance; the downside is increased maintenance. The good news is that you don’t have to bring your car in for this service, the valve clearance adjustment can come to you by choosing to have one of the many professional technicians available through YourMechanic come to your home or work.

Low oil pressure might be the cause of those ticking sounds. When vital engine components don`t get adequate lubrication, it might cause other problems, and the engine starts to make these noises. A broken valve train component, such as lifters or cam followers, can also cause ticking, tapping, or clicking sounds.
Engine Clicking (or Ticking) Sounds
The engine clicking sound can be caused by a leak in your engine, a faulty oil pump, or insufficient oil in the reservoir.
An engine with low oil or low oil pressure can make a ticking noise due to a lack of lubrication. If you are low on oil, it may indicate either oil consumption or an oil leak, both of which should be addressed as soon as possible. If you have low oil pressure, you will likely get a warning on the dash.
We often encounter engines that have a cold-start knock or ticking noise. In this case, the 3.5-L V6 engines installed in various Honda models can make a knocking or ticking noise at idle and only when warm.
The engine`s cylinder head uses a series of lifters in order to open and close the valves. These lifters can get worn out over time, which inevitably causes a metal-on-metal ticking noise at idle and upon acceleration.
It might be a battery or alternator problem.
If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn`t have enough juice to stay powered. So instead, it rapidly turns on and off and produces a clicking noise!
Lifter Ticking
If a lifter goes flat, or won`t hold pressure, you`ll likely hear it begin to make noise. Often, a lifter tick will be most prevalent as soon as you start the engine, and may get quieter or disappear completely as the engine warms up. You may also notice the sound is more prevalent at idle.
The ticking noise may be coming from the alternator itself, or from the drive belt that powers it. When the vehicle is cold it can be loud and need a moment to warm up. If the belt or the pulley are failing, you will need to replace them. You can test the belt for extra play to make sure it is tight.
The excess oil can create air pockets in the oil, causing it to foam and reducing its effectiveness in lubricating engine components. This results in unusual engine noises, including knocking, tapping, or ticking sounds.
When the timing belt starts to wear out, it may create a ticking sound inside the motor. This warning sign may also be an indication of low oil pressure or the engine not having the proper amount of lubrication.
The revolving parts rub against each other as the friction from low lubrication increases. So if happen to use a different oil filter, it could be the reason why your engine is making a ticking noise after an oil change.
A knocking sound coming from your car`s engine can indicate an issue with the crankshaft journal and bearing, which are hitting each other. It`s not exactly a simple fix, so auto shops tend to charge anywhere from $2,000 to $3,000. Some repairs can run up to $4,000 if the damage is severe.
One of the first abnormal noises produced by an engine low on oil is often that of a ticking nature. This occurs as an engine`s critical top-end components are starved for vital lubrication. If oil is not quickly added or a complete oil change done, significant engine damage can occur as a result.
Adding more oil will make the noise go away, but it won`t solve the underlying cause of the noisy engine – the oil leak.
Most people call this a pinging or rattling sound. This noise is caused by an air/fuel mixture in the engine cylinder being ignited prematurely by the heat of compression as the piston is moving up on the compression stroke.
The most obvious symptom of a faulty hydraulic lifter is the noise it creates in your car`s engine. You can usually distinguish the faulty lifter by the distinct sound. Instead of a knock or ping, a faulty hydraulic lifter will usually make a sound more reminiscent of a tapping sound.
If you ever hear growling or whining noises coming from under the hood, you could have alternator problems, which should be checked out by a professional ASAP. This growling or whining sound happens when the belt that turns the alternator`s pulley becomes misaligned or rubs against the side of the pulley.
In some engines, clicking and ticking noises may occur when something as simple as low oil level is present, but may also indicate a valve sticking, loose cam chain or other valve train problems. A clicking or clattering sound while in motion may also indicate a primary drive chain in need of adjustment.

A knocking or ticking noise on some Honda 3.5L V6 engines occurs when the rocker shaft bridge has excessive clearance from the factory. We often encounter engines that have a cold-start knock or ticking noise.
